Tony Nicklinson suffered a massive stroke in 2005 that left him with locked-in syndrome -- he is completely paralyzed and unable to speak, but his mind was unharmed.

Now, the 57-year-old has become the first person to tweet using only the movement of his eyes:

Hello world, I am tony nicklinson, I have locked-in syndrome and this is my first ever tweet.

Nicklinson, who lives in the U.K., will ask the high court Monday to argue that a doctor should be allowed lawfully to end his life. He says his current state is "dull, miserable, demeaning, undignified and intolerable."
